Universal Plug and Play (UPnP) is a common peer-to-peer network connection architecture for PCs and smart devices.

For an intranet computer, UPnP enables the NAT module of the gateway or router to do automatic port mapping, mapping the listening ports from the gateway or router to the intranet computer.
